PhoneGap Serve stuck on fontawesome.woff2browsing

I was debugging my PhoneGap app in the browser, with the usual “phonegap serve” command, and suddenly Chrome crashed.
Then I restarted my PC, tried the CLI command again, but now it keeps freezing at a point, and I can’t get it to go further.

I deleted the directories form the Onsen framework, and copied them back again, but it still freezes there.
Is this a caching issue?
